چکیده
CdCl2 dissociates in dimethylformamide into the species C d(D M F)62+, C dCl(DM F)5+ and CdCl3~ as determined by ll3Cd NM R spectroscopy. "B and ll3Cd N M R spectra o f M BH4/ CdCl2 solutions in this solvent show the presence o f complexes [CdCl2_„(BH4)n+|]with rapid exchange o f BH4~ and CL at ambient temperature. There is no evidence that Cd(BH4)2 is formed in a metathetical reaction. The crystal structure o f CdCl22 D MF has been determined. It is a coordination polymer containing hexacoordinated Cd atoms with the DM F molecules in cw-position. Coordination o f D M F occurs via the carbonyl oxygen atoms.

An investigation on the effect of acetone and DMF as solvent on synthesis of P2O5-CaO-Na2O-TiO2 glass powder by sol-gel method
The sol-gel synthesis method allows greater control over glass morphology at a relatively low processing temperature (200 °C) in comparison with melt-derived glasses. In present study, phosphate-based glasses with the general formula of (P2O5)55-(CaO)25-(Na2O)10-(TiO2)10 was synthesized via a novel and facil...

In this paper, we report the crystal structure and magnetic properties of the cyano-bridged gadolinium-tungstate bimetallic assembly, GdIII(DMF)6[WV(CN)8](DMF =N,N-dimethylformamide). X-Ray single crystal analysis shows that this compound crystallizes in the monoclinic system of space group P2(1)/c with cell constants a= 16.40(2)A, b= 11.08(1)A, c= 21.18(2)A, beta= 91.09(8) degrees, and Z= 4.

The synthesis of several phosphine Cu(I) complexes is reported, and their reactivity towards the solvents ethylenediamine (en) and dimethylformamide (dmf) has been investigated. CuX(PPh3) [X = Cl (1), Br (2)], CuCl(PCy3) (3) and CuCl(PPr3)n [n = 1 (4), 2 (5)] were prepared according to adapted literature procedures. The complexes CuCl(PPr3)n were obtained in crystalline form from a hexane solut...
متن کاملN,N-dimethylformamide-induced phase separation of hexafluoroisopropanol-water mixtures.
We found that addition of N,N-dimethylformamide (DMF) induces phase separation of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP)-water mixtures. The phase diagram of a DMF-HFIP-water ternary system at 298 K showed that phase separation occurs in a closed-loop area in the water-rich mole fraction range of x(H(2)O) > ∼0.4. To clarify the mechanism of DMF-induced phase separation of DMF-HFIP-water mixtu...
